Title: Corona discharge treatment of plastics materials
IPC: H01T19/04
Filed: 1979-01-10
Abstract: Device for processing plastics film surfaces by electric discharges distributed over the film passing between two electrodes between which the discharges occur. One of the electrodes is divided into a plurality of elementary operative electrodes (14), which, in conjunction with a dielectric (11) and a plate (13) connected to a high voltage source (1), effectively form a plurality of parallel capacitors. The other electrode may be a roller (15A) or bar. The working width may be varied by inserting dielectric members between the electrodes, by altering the length of the bar electrode, or by energising only selected electrodes (14) by correspondingly dividing the plate (13) and connecting to the voltage source via a commutator. <IMAGE>

Title: Multi-purpose vehicle
IPC: B62D7/14
Filed: 1979-01-29
Abstract: A multi-purpose four-wheel drive vehicle is disclosed having four-wheel steering. A hitch (68) is slung below the vehicle body between the front and rear wheels or forward of the front wheels. By slinging the hitch in this manner the force applied to the rear wheels and also the front wheels, to move the vehicle forward, is given a component towards the ground so that the heavier the load towed and the greater traction required to pull the load the greater the vertical force applied to the wheels thereby increasing traction between these wheels and the ground. The multi-purpose vehicle incorporates a relatively high ground clearance which is achieved by employing four vertical axles and wheels situated at the four corners of a main frame body of the vehicle. The vertical axles are situated in respective spaced-apart leg post members (54a to 54d), each leg post member being rigidly interconnected by two spaced-apart longitudinally extending frame members (50,52) and two spaced-apart transversely extending frame members (56,58). At least three (50,52,56) of the frame members are of torsionally resilient construction. The vehicle incorporates a belt or chain and sprocket transmission for driving the vehicle which can also be used as an amphibious transporter. <IMAGE>

Patent GB-2031596-A (GB)
Title: Leaf focal plane shutter for single lens reflex cameras
IPC: G03B9/42
Filed: 1979-07-20
Abstract: The focal plane leaf shutter is so arranged that the closing leaves in their starting position are closed under the side of the film gate away from the viewfinder. During the exposure process, the opening and closing leaves start out towards the viewfinder. The closing leaves in their starting position beyond the film gate show a greater number and lesser width than the opening leaves starting off upwards towards the viewfinder from their starting position covering the film gate. In this way, the lower camera space can correspondingly be made smaller. A continuing decrease in the lower camera space can be achieved if the width of the closing leaves is less than the width of the opening leaves, so that the closing leaves in their closing position covering the film gate overlap each other in the direction of movement by a total which is less than the total by which the opening leaves overlap each other in their starting position covering the film gate, and that at least the opening leaves automatically return to their starting position after the exposure process.
